Abstract: An apparatus for maintaining an effective concentration of alkaline detergent in an aqueous medium in a warewashing machine, which apparatus comprises a batch-fill warewashing machine having an aqueous rinse system, an alkaline detergent dispenser and a sump sized for a predetermined volume of an aqueous solution of the alkaline detergent in the aqueous medium; a source of the aqueous medium fluidly connected to the rinse system; means for controlling the flow of the aqueous medium through the rinse system; diverting means for obtaining a predetermined portion of the aqueous flow from the rinse system and for directing the diverted portion through a metering cap and volume control to the alkaline detergent dispenser, thereby to dissolve the alkaline detergent; and means for directing the dissolved alkaline detergent to the sump; wherein the detergent is dispensed only in a rinse cycle and an effective concentration of alkaline detergent is maintained in the warewashing machine sump.
